Bloom War is an adult visual novel made by ATH Games in Ren'Py. It uses a 3D rendered art style and presents a world where certain girls are unusually large. You play as a young man, or a futa character, who discovers that they may be more than they appear. The story mixes transformation, harem, and milf themes, and it can be played as a desktop or mobile visual novel.
The current build is v0.24, dated September 3, 2026, and development is ongoing. It is available on Windows, Linux, Mac, and Android, in English, with no censorship. The v0.20 update focused on the protagonist's shrink route, where Kammy or Jayne takes them to school, and it notes a choice to tell Kammy not to grow while talking with Rebecca by the pool.
Developer's description
In a world where some girls are massive in many ways, one young man (or futa) finds out they may be more than they seem.

v0.20
I'm finally back with a new Bloom War update. I had to rewrite a bunch of the old code in order to get rid of the map stuff, but it freed up some file space and now it should be a bit less tedious to get through those parts if you're trying to get to a new route. As for the content, it focuses on the MC shrink route where the MC get taken to school by Kammy or Jayne, so you'll need to make sure to tell Kammy to not grow when she's talking with Rebecca by the pool.
v0.19
Notes: This update is a standalone update, meaning it only contains the new content from the previously updated route.
v0.18
The new content for this update is in the growth route after you go to the cafe.
I've also added a new feature to the gallery where you can click a locked imaged to get a hint as to how to unlock it.
v0.17
For this update, I've started implementing sprites for the characters in order to try to limit the amount of work I need to do for each update. I think it's defiantly made it easier, and I think I can still optimize the process further. I ran into a couple issues when trying to translate things over to the new process, but I think I got everything figured out. But as always, let me know if you run into any errors. Also, due to using sprites and not full images for most of the scenes, the gallery feature won't really work as it is anymore, and hasn't been updated for this update. I will probably need to change hoe the feature works, and I've been thinking of doing more of a route map instead of a gallery in order to give players more information on how to get to the routes they haven't seen yet. I'll try to figure out the best way to do that for the next update. Also, since the gallery feature isn't updated, I will let you know which routes have been updated here.
Shrink Route:
Can now choose between Rias, Kammy, and Jayne to go with after shrinking.
Rias' giantess growth route has been extended to feature a scene with Melody and Ariel.
Kammy and Jayne now both have options to take MC with them to school. Note that the option to go to school with them is only available if they haven't grown too much.
Going with Kammy can let the player make her grow again in MC's bedroom, or go somewhere with MC. (Casino or school)
Kammy can take MC with her to the casino where she will meet Roxane, Wendy, and Natalie, as well as Sarah.
A game of roulette will decide who MC goes with., setting up routes for the other characters there. Only Kammy's route there goes beyond that.
If MC never told Jayne to bring swimsuits to school, causing Sarah to owe Kammy a favor, Sarah will join Kammy in her route at the casino.
Growth Route:
Continues from the last scene with Madison.
Rebecca brings MC, Norah, and Allison back to the cafe to get started on her plan to make MC huge.
Normal Route:
Added a new option to the futa only version scene with Sarah and Kammy after Kammy takes Sarah's size.
v0.16
For this update, the new content is for the MC normal route, focusing on Sarah. The new content takes place after Sarah wins the dodgeball game, or if MC wins and chooses to hang out with Sarah. Also, the content available will depend on whether or not Jayne and Kammy brought swimsuits to school and whether or not Jayne and Kammy are small enough to attend school. Be sure to check the gallery if you are wondering if you missed any content.
v0.15
Extended routes and new growth for:
Kammy
Laurah
Allison
Norah
Madison
Set up routes for:
Silvia
Scarlet
New Character
Added new text color for certain option to signal major story paths
Finished gallery feature
Minor rewrites
Changed "EyePatch" system
v0.14
This is largely a set-up update for the routes for each of the girls at the school. This update has a lot of different options, so I'll explain how to get to them. This update continues the "normal" route, so you will need to select the "I'll pass" option during the scene with Sasha asking to shrink you. Also, the content in the update would change based on if you chose to let Kammy grow or not. If you chose to let Kammy grow them, she and Jayne won't be present at the school. Also, during gym class, the winner will be determined by your choices, so try other ones if you want someone else to win.

Balbaar2024-11-11★★★★★
Well, suprisingly enough I actually had a bit of fun playing through this game. I say surprisingly because things like body transformation, sizeplay and ridiculous proportions (and I do mean ridiculous, holy hell..) which also includes inflation to the point…
Rogue212024-08-17★★★★★
Bloom War is definitely one of the crazier and out there games I've come across. Don't get me wrong, futa is great and all but the game pushes some fetishes to the limits and for the most part, done right…
Goddess Hylia2024-03-17★★★★★
It is fairly basic Ren'Py visual novel, but if you are into futanari, giantess, and especially expansion/inflation content, please give it a chance. It has shockingly decent plot and the NSFW content is even better, and there are even some…
